Operation Mathematics

This resource can be used to practice finding common denominators. An example demonstrates how to find the least common multiple, and students are given 6 practice problems. A second example demonstrates how to find the least common denominator (LCD), and students are given 6 more practice problems. A key is included.

These guided notes should be used as the first lesson in a unit on integers. Students will practice graphing integers on number lines, learn about the difference between positive and negative, write integers based on real-world situations, and evaluate absolute value expressions. Numerous example problems are embedded throughout the notes. A key is included.
